IMPROVED COOKING-STOVE.

ESpeciiication forming part of Letters Patent No. 45,432, dated December13, 1864.

To ctZZ whom, it may concern:

Beit known that I, MosEs POND, a resident ot' Boston, in the county ofSuffolk and State ot' Massachusetts, have made a new and usefulinvention of certain Improvements in Cooking- Stoves; and I do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawings, of which- Figure 1 denotesa longitudinal and central section of a stove provided with myinvention. Fig. 2 is a transverse section taken through the fireplace.Fig. 3 is a transverse section taken through the oven. Fig. 4 is atransverse section taken through the back tlue dovetail plate orpartition, and representing the arched slantin g plate at the bottomthereof. Fig. 5 is a front end elevation, and Fig. 6 a side elevation,of the stove. Fig. 7 is a transverse section of the fire-place auditslire-brick lining, such section being taken through one of the airheating and receiving chambers applied to the front plate. Fig. 8 is arear view of one of the end parts of the fire-brick lining.

The nature of my invention consists of an improved lire-proof lining orlinings to the replace, the same having a channeled, recessed, orchambered back, substantially as hereinafter described; also, in thearrange ment and combination of a separate air-heating chamber with thetire-place and oven of a cookingstove in such manner as to surround thefireplace and be capable of receiving air from the external atmosphereand heating it and afterward discharging it into the oven, the saidairlheating chamber having not only one or more air-induction passagesleading into it, but one or more aireduction passages leading from itinto the oven also, in the combination and arrangement of one or moreair-,heating chambers with the front plate ofthe stove, and with theoven and the chambered lining or main airheating chamler, and thepassages for leading air into and through the said chamber or chambersand li dug and into the oven; also, in the combination of a slantingarched plate at the bottom ot' the dividing back iiue plate with suchilue plate, and the curved partition leading underneath the oven, ashereinafter described, the purpose of the slantin g arched plate beingto enlarge the oven-tlue, so as to increase the l B the grate, O theash-chamber, and D the oven, ot' a stove, they being arranged togetheras shown in Fig. l.

The fireplace has a lire-brick, stone, or other suitable lining, E,which in its rear surface is to be chambered or recessed, as shown at a,the chamber a being horizontal, and extending throughout each side andend portion of the lining. One or more air-holes, b, made through thefront plate,c,of the stove lead air into the chamber a of the lining,which, after having circulated about the lining or between it and theplates of the stove, will escape into the oven by or through one or moreorifices, c', made through its front side. The holes b are covered by,one or more guard-plates, d, which are so applied to the front plate ofthe stove as to form between it and such guard plate or plates one ormore auxiliary air heating chambers or channels, c, open at bottoln. Theair rushing upward into such auxiliary chamber or chambers e will becomemore or less heated therein before passing into the induction hole orholes b. Thus, while these auxiliary chambers c serve to heat the air,the plate or plates d act as guards for the induction-holes and toprevent heat radiated from the front plate ot' the stove from being aninconvenience to an attendant while standing or stooping immediately infront or close to the stove.

Over the top plate of the oven there is a line, F, which also descendsin rear of the oven, as shown at F', and opens into ues G Gr, whichcourse directly underneath the oven and from the rear to the frontthereof, such tlucs being formed in part by an arched plate, IzI, whichis extended underneath theoven and rests at its two opposite edges onthe bottom plate, I, ot' the stove. With such bottom plate the archedplate forms a return-due, K, which at its rear leads into an ascendingdischarge-line, L, (formed by the back plate, f, of the stove and adividing back line plate, 9,) and at its front opens out of the flues GG.

The junction of the plates H and g is effected by a slanting archedplate, k, arranged as shown in the drawings, such slanting plate kserving the purpose or purposes hereinbet'ore stated. An opening, l, inthe upper inclined part ofthe plate g is provided with a damper, m,suoli opening being for the purpose of dis- I charging the smoke intothe escape-flue Without rst causing it to circulate against the rear andbottom of the oven.

In the operation ot' the above described stove the air which goesthrough the recesses or chambers of the lining serves to `absorb heatfrom the lining, and thereby prevents such lining from becomingoverheated.

I claiml. The improved stove as madewith the nir- Witnesses:
